LU-14895 client: allow case-insensitive checksum types

The current t10ip4K and t10crc4K checksum types use an upper-case 'K'
in the name, unlike the other checksum types which are all lower-case.
This is distinction is difficult to see in some fonts, and can cause
usage errors.  Accept upper-case variants of the checksum type names.
